Lava room skip instructions

Turn on lightning armor
Roll up the left wall in spider ball
Place a bomb below the spikes, needs to be close enough that it can still hit you when you are inside the spikes
Wait for a little bit
When the bomb is about to go off spider ball into the spikes
If you did it right you will get hit by the bomb and go through the spikes
When you're above the spikes let go of l and repress it to stick to the wall. Don't let go of L too early otherwise the spikes may eject you to the right instead of bomb jumping through it.
